CROSS-REFERENCE TO RELATED APPLICATION

This application is based on and claims priority under 35 U.S.C. § 119 to a Korean patent application filed on Nov. 27, 2015 in the Korean Intellectual Property Office and assigned Serial number 10-2015-0167100, the disclosure of which is incorporated by reference herein in its entirety.

TECHNICAL FIELD

The present disclosure relates generally to a question and answer (QA) processing method in an electronic device and an apparatus therefor.

BACKGROUND

An electronic device may include a QA system which supports processing answers to user question items. The QA system may receive a command such as s voice or text from a user and may analyze the received user command via a recognition engine. The QA system may extract a keyword suitable for the user command and may extract founded contents corresponding to the extracted keyword.

As the QA system simply outputs a short answer to a command such as a voice or text input from the user, it may output an answer which does not correspond to the intention of the user. For example, since the QA system simply outputs only a specified answer to a user command, there may be a small amount of information to be obtained by the user or accuracy of information to be obtained by the user may be low. Thus, it is difficult to provide efficient and accurate information. Also, since the QA system outputs only a specified answer, answers which do not correspond to user conditions may be provided.

In various embodiments, at least one of the components of the processor 120 may be omitted from the processor 120, or another component may be additionally included in the processor 120. The various modules may be realized in hardware (e.g., circuitry), software, firmware or a combination of these.

The question processing module 121 may collect, for example, a user command signal via an audio device 110 or a communication interface 170 of FIG. 1. In this regard, the question processing module 121 may control activation or deactivation of the audio device 110. When receiving a request to transmit a user command signal from an external electronic device 200 of FIG. 1, the question processing module 121 may receive the user command signal and may analyze the received user command signal. The question processing module 121 may recognize a command for the collected command signal and may convert the command into text. The question processing module 121 may extract important words from the converted text, may analyze the extracted words, postpositions, and the like, and may extract an answer associated with a question. In this regard, the question processing module 121 may use a question database 131 and/or an answer database 133.

According to various example embodiments, the question processing module 121 may omit converting a question received in the form of text via the communication interface 130 into text. According to an example embodiment, the external electronic device 200 may collect a user voice signal, may convert the collected user voice signal into text and may send the text to the electronic device 100. For example, the external electronic device 200 may obtain information of a noise level of an audio signal collected by its microphone. If the noise level is greater than or equal to a specified level, the external electronic device 200 may filter a noise of obtained audio information, may convert the filtered audio information into text, and may send the text to the electronic device 100.

According to various example embodiments, the question processing module 121 may obtain information of a noise level in collected audio information. If a noise level is greater than or equal to a level, the question processing module 121 may output a user interface for entering text. The question processing module 121 may determine a distance between a point where a collected voice signal is spoken and an electronic device 100 of FIG. 1 is greater than or equal to a specified separation distance. If the separation distance is greater than or equal to a specified distance, the question processing module 121 may output a user interface for entering text. According to various example embodiments, the question processing module 121 may identify stored user information and may output a user interface associated with automatically entering text. For example, the question processing module 121 may obtain user information of the external electronic device 200 which establishes a communication channel. If the user of the external electronic device 200 is a user who cannot input a voice command, the question processing module 121 may output a user interface associated with automatically entering text.

According to various example embodiments, the question processing module 121 may determine at least one of attributes information of a question and/or attributes information of an answer using the question database 131 and/or the answer database 133. According to various example embodiments, if there is no data corresponding to an analyzed question in the question database 131 and/or the answer database 133, the question processing module 121 may send the data to a server and may collect answer or link information corresponding to the data, address information of the server, or storage location information stored in the server. The question processing module 121 may collect address information or link information of the electronic device 100 which stores an answer corresponding to the analyzed question.

The question processing module 121 may control activation of a sensor 180 of FIG. 1. For example, if a user command signal is collected, the question processing module 121 may activate the sensor 180 and collect context information. According to an example embodiment, the question processing module 121 may collect face recognition information of the user, distance information (e.g., information about a separation distance between the electronic device 100 and the user), information about a direction observed by his or her face, information about a location where the user is located, or the like.

The additional information generation module 123 may generate, for example, additional information based on attributes information associated with an obtained answer or question. The additional information generation module 123 may collect another information which belongs to a classification (or category) of an obtained answer. If attributes information of an answer is about money, the additional information generation module 123 may generate another answer which belongs to an economy classification, for example, information about conditions of the stock market or conditions of the real estate as additional information. If the attributes information of the answer is about food, the additional information generation module 123 may generate another type of food associated with food found as the answer or a characteristic of the found food as additional information.

According to various example embodiments, the additional information generation module 123 may generate additional information corresponding to a specified condition based on attributes information and context information. For example, if an answer associated with a length is found, the additional information generation module 123 may obtain height information of the user from the context information, and may generate additional information about a correlation between the obtained height information and the length. According to an example embodiment, if a question is about a height of Mount Everest and if an answer to the question is 8848 m, the additional information generation module 123 may generate a relationship (e.g., a rate) between a height of the user and the height of the Mount Everest as additional information. The height of the user may be obtained from previously input user information or may be obtained by analyzing an image of the user, captured by the sensor 180 (e.g., an image sensor).

According to various example embodiments, if a name of a specific person is found as an answer to a question about the specified person, the additional information generation module 123 may generate information about a relationship between the corresponding person and the user (e.g., a person who has the same family name, a person who graduates from the same school, or the like) as additional information. In this operation, if a plurality of persons who have the same family name or graduate from the same school are found, the additional information generation module 123 may select a person having awareness of a level or more, may collect person information about the selected person to generate the collected person information as additional information. For example, the additional information generation module 123 may send a name of a person to a server and may generate person information about a person found the number or more of times among persons found using the corresponding name as additional information.

According to various example embodiments, if a name of a specific electronic device is found as an answer to a question about the electronic device, the additional information generation module 123 may generate a relationship between the found electronic device and an electronic device of the user (e.g., information indicating whether the found electronic device interworks with the electronic device of the user, version information, and the like) as additional information. Alternatively, the additional information generation module 123 may generate a method of using the found electronic device as additional information. The additional information generation module 123 may generate additional information based on price information, size information, and the like of the found electronic device.

According to various example embodiments, the additional information generation module 123 may generate additional information based on answer history. For example, the additional information generation module 123 may manage asked questions and answers to the corresponding questions as history. According to an example embodiment, the electronic device 100 may perform an electronic book (e-book) read function stored in a memory 130 of FIG. 1. In this example, the electronic device 100 may store and manage data about when the user read any e-book. If a request to read a new book occurs, the additional information generation module 123 may generate a description, a picture, or audio information associated with words included in the new book as additional information. For example, the additional information generation module 123 may generate an image which is associated with a specific word included in the new book and is included in a book having previously read history as additional information.

According to various example embodiments, the additional information generation module 123 may classify user information according to users and may store and manage the classified user information, in connection with answer history. For example, the additional information generation module 123 may collect user information for each family member (e.g., personal information for each user, audio feature information for distinguishing a speaker, preference information, information about an electronic device which is being operated for each user, and the like). The additional information generation module 123 may classify answer history according to users and may store and manage the classified answer history, while providing questions asked for each user and answers to the corresponding questions.

When an answer to a question of a specific user is selected, the additional information generation module 123 may generate additional information in a different way based on a grade (or a relationship, a location, and the like) of the corresponding user. For example, the additional information generation module 123 may generate additional information associated with a question and answer of a father or a mother among family members and additional information associated with a question and answer of a son or a daughter in a different way and may output the generated additional information. According to an example embodiment, if a schoolchild asks about a tomorrow schedule, an answer may be school attendance, and the additional information generation module 123 may generate a class schedule table as additional information. If a mother who has a schoolchild asks about a tomorrow schedule, an answer may be the same school attendance as an answer of the schoolchild, the additional information generation module 123 may generate additional information including a class schedule table of the schoolchild and a schedule table associated with traffic guidance.

According to various example embodiments, when generating additional information associated with exercise, the additional information generation module 123 may provide differentiated information based on user information. The additional information generation module 123 may generate additional information in which a form of exercise to be performed or a goal amount of exercise is set in a different way, based on user information. For example, if receiving a question item about a yoga posture, the electronic device 100 may output an answer about various yoga postures (e.g., at least one of text information, audio information, or image information). The additional information generation module 123 may provide a relatively easy yoga posture or a relatively difficult yoga posture as additional information based on user information. The additional information generation module 123 may provide different yoga postures as additional information based on exercise history for each user, an amount of usual exercise, and the like.

According to various example embodiments, when generating additional information associated with exercise, the additional information generation module 123 may generate the additional information based on answer history. For example, when new exercise is performed, the additional information generation module 123 may obtain previously performed exercise history (e.g., obtained through answer history) and may generate additional information to refer to a similar exercise posture or operation in connection with a new exercise posture or operation. In this regard, the additional information generation module 123 may extract a feature point for the new exercise posture or operation and may search for history of an exercise posture or operation having a matching rate of a specified level or more. If there are a plurality of found information, the additional information generation module 123 may first provide an exercise posture or operation with a high matching rate or may provide all of found information in the form of a multi-view.

According to various example embodiments, the additional information generation module 123 may provide additional information for each stage in connection with exercise information. For example, if a question about exercise occurs, the electronic device 100 may output a text description or image associated with various exercise types as an answer. When providing information about various types of exercise (e.g., a push-up, sit-up, a chin-up, and the like), the additional information generation module 123 may generate a relatively easy or difficult type of exercise or an amount of the exercise as additional information and may provide the additional information, based on user information (e.g., a body condition of the user, an amount of usual exercise, and the like).

According to various example embodiments, the additional information generation module 123 may configure analects based on expressions frequently used by the user and may generate additional information based on the analects. For example, if generating the additional information, the additional information generation module 123 may replace words having the same meaning among words included in the additional information with words included in the analects of the user. Thus, the additional information generation module 123 may support describing information using words or expressions which are more familiar to the user.

According to various example embodiments, when referring to information associated with generating additional information, the additional information generation module 123 may use a database stored in at least one external electronic device. For example, if a word (or sentence) associated with generating additional information is found, the additional information generation module 123 may send the corresponding word to at least one external electronic device and may collect information associated with the corresponding word from the external electronic device. The additional information generation module 123 may send attributes information associated with a question or answer to the external electronic device and may collect information corresponding to the attributes information among information stored in the external electronic device.

The additional information generation module 123 may select a specified external electronic device based on attributes information of a question or answer and may share a database of the selected external electronic device. For example, the additional information generation module 123 may share a database stored in a memory of at least one of external electronic devices, such as a refrigerator, a washing machine, a microwave, a television (TV), an audio device, a projector, and a desktop computer, or the like, which are connected or may be connected over a communication channel. In this regard, the electronic device 100 may store and manage a mapping list of mapping at least one external electronic device for each attributes information. The additional information generation module 123 may generate additional information based on the collected information or the shared database.

The output module 125 may output, for example, an answer to a question to a specified device (e.g., the external electronic device 200). The output module 125 may convert a found answer into a voice signal and may output the converted audio signal via an audio device 110 of FIG. 1. The output module 125 may output the found answer via an audio device of the external electronic device 200. According to an example embodiment, if there is the external electronic device 200 within a distance with respect to a location where the user is arranged, the output module 125 may control the external electronic device 200 to output an answer via the corresponding external electronic device 200. When outputting the answer, the output module 125 may output the answer (e.g., output the answer as audio information or screen information) to a plurality of specified devices (e.g., the at least one external electronic device 200).

According to various example embodiments, the output module 125 may change a form of an answer to be output, based on a characteristic of the answer to a question. For example, if a found answer is a short answer, the output module 125 may convert the answer into a voice signal and may output the converted audio signal over the audio device 110. If the found answer is a descriptive answer, the output module 125 may output the answer as screen information (for this purpose, convert the voice signal into text and output the text), while converting the corresponding answer into a voice signal and outputting the voice signal. Also, the output module 125 may determine whether a specified condition is met, based on a characteristic of an answer to a question. If the specified answer is met, the output module 125 may output the corresponding answer to a specified device (e.g., the external electronic device 200). If a time series answer is found, the output module 125 may output part of the answer. If a specified condition (e.g., a condition in which specified context information is obtained) is met, the output module 125 may output next answers.

According to various example embodiments, if an answer including an image or a formula is found, the output module 125 may output screen information on a device (e.g., the electronic device 100 or the at least one electronic device 200). In this case, the output module 125 may output audio information of providing that the answer is output as the screen information. The output module 125 may output audio information of providing notification that the answer is output to any device (e.g., the specific external electronic device 200).

According to various example embodiments, the output module 125 may perform output retry based on a monitored result. For example, the output module 125 may analyze audio information collected via a microphone of the electronic device 100 and may determine that audio information of a specified form is collected. If the audio information of the specified form is not collected and if a specified time elapses, the output module 125 may output previously output information again. According to an example embodiment, the output module 125 may classify and output a specified song at intervals. The output module 125 may output the song during a first interval and may collect audio information spoken by the user. If a form of the audio information is identical to the specified form, the output module 125 may output the song during a next second interval. According to various example embodiments, the output module 125 may apply comparison criteria for audio information collected for each user information in a different way. For example, the output module 125 may apply a condition of a specified form in a different way based on a song career of the user (e.g., obtained by a user input), previous singing history (e.g., score history for each song), or the like. If the song career of or the previous singing history is relatively fewer, the output module 125 may provide a relatively lower (or weaker) condition. Thus, although the user sings relatively badly (e.g., although there is many times a beat or pitch is wrong), the output module 125 may pass a current interval and may output a next interval.

According to various example embodiments, the electronic device 100 (e.g., the question processing module 121 of the processor 120) may receive a question in connection with a game using assembly blocks and may obtain an assembly method for each stage as an answer in response to the question. The output module 125 may analyze an image for a form of assembling assembly blocks and may determine whether a current stage is any assembly stage based on the analyzed image. The output module 125 may output an assembly description of a next stage for each assembly stage (e.g., a description of a form of necessary blocks, the number of the necessary blocks, and a location where the blocks should be arranged).

According to various example embodiments, the output module 125 may perform classification for each user based on a collected voice command. The output module 125 may output a timbre, a tone, a tempo, and the like of information to be output for each user in a different way. For example, if the user is a child, the output module 125 may output an answer or additional information using a voice of a relatively sonorous tone or at a relatively slow speed.

According to various example embodiments, the output module 125 may change a type of an external electronic device for outputting an answer or additional information, based on the user which inputs a question. For example, the output module 125 may send an answer or additional information to an electronic device used by the user who inputs a question. In this regard, the output module 125 may search for a currently connected user electronic device or may connect a communication channel with an electronic device registered in connection with the user (e.g., perform pairing). If a plurality of electronic devices are registered in connection with the user who input a question, the output module 125 may send an answer or additional information to an electronic device registered as a wearable device.

According to various example embodiments, the output module 125 may collect user information or information used to generate additional information from a memory of the connected electronic device. The output module 125 may output an answer or additional information based on a voice. If information such as an image or a formula is included in the answer or additional information, the output module 125 may send the corresponding answer to an electronic device associated with the user.

The exercise control module 127 may control, for example, an exercise function of the electronic device 100. If a direction in which a voice signal of the user is collected is detected based on a plurality of microphones, the exercise control module 127 may control (e.g., rotate or move) the electronic device 100 such that a face of the electronic device 100 (e.g., a region where a display 160 is arranged or a region where the sensor 180 (e.g., a camera or an image sensor) is arranged) looks at the direction in which the voice signal of the user is collected. If a voice signal of the user is of a level or less, the exercise control module 127 may control the electronic device 100 such that the electronic device 100 moves to a point at which the voice signal of the user is spoken. The exercise control module 127 may be moved in a form on the user to capture an activity state of the user. The exercise control module 127 may be moved to a location where an image of a specified image is capture, based on a plurality of images collected at various angles.

According to various example embodiments, at least some of the question processing module 121, the additional information generation module 123, the output module 125, and the exercise control module 127 may be implemented with software, firmware, hardware, or at least two or more combinations thereof. At least some of the question processing module 121, the additional information generation module 123, the output module 125, and the exercise control module 127 may be implemented (e.g., executed) by a processor (e.g., the processor 120). At least some of the question processing module 121, the additional information generation module 123, the output module 125, and the exercise control module 127 may include, for example, a module (e.g., including circuitry), a program, a routine, sets of instructions, a process, or the like for performing one or more functions.

FIG. 3 is a flowchart illustrating an example of a QA processing method according to an example embodiment.

Referring to FIG. 3, in connection with the QA processing method according to an example embodiment, in operation 301, a processor 120 (e.g., a question processing module 121) of FIG. 2 may collect and analyze a voice. For example, the processor 120 may activate an audio device 110 of FIG. 1 to collect a user voice signal. The processor 120 may receive a user command signal from a specified external electronic device 200 of FIG. 1 via a communication interface 170 of FIG. 1. If an input is a voice, the processor 120 may convert the voice into text based on a voice recognition function. In this regard, the electronic device 100 of FIG. 1 may include a voice recognition program and a voice recognition database. The processor 120 may extract a subject, an object, a predicate, and the like from the converted text and may compose a sentence using the extracted information. The processor 120 may extract words from the converted text. The processor 120 may search for a response corresponding to the sentence configured based on the text or the extracted words. In this regard, the processor 120 may search a question database 131 and an answer database 133 of FIG. 1 for an answer corresponding to an extracted question. According to various example embodiments, if there is no data corresponding to a question in the question database 131, the processor 120 may send an extracted question to an external server via the communication interface 170 and may receive an answer corresponding to the question from the external server.

In operation 303, the processor 120 (e.g., the question processing module 121) may determine whether the analyzed result is a specified short-answer question. In this regard, as described above, the processor 120 may obtain information of a length of an answer using the question database 131. If the text length of the answer is within a specified length (e.g., if the answer is configured with one word, if the answer is a compound word having one word meaning, or if the text length of the answer is within 10 letters), the processor 120 may determine the analyzed result as the specified short-answer question.

If the analyzed result is the specified short-answer question, in operation 305, the processor 120 (e.g., an additional information generation module 123 of FIG. 2) may generate additional information based on attributes of a question or attributes of a short answer. For example, the processor 120 may collect attributes information about a question or an answer based on the question database 131 or the answer database 133. The processor 120 may collect information associated with the same attributes information (e.g., a main classification or a subclassification) as the collected attributes information as additional information. For example, the processor 120 may generate a news article, user search history information, and the like which belong to the same classification as the attribute information as additional information.

According to various example embodiments, the processor 120 may collect context information and may generate additional information which includes the collected context information and the attributes information in common. For example, if a question associated with a location or a place name is received, the processor 120 may collect current location information as context information. The processor 120 may generate additional information associated with a current location (e.g., news associated with the current location, building or place name information corresponding to the current location, and the like). The processor 120 may compare the answer with the context information and may generate additional information corresponding to the compared result. For example, if a question associated with a height, a length, or an area is received, the processor 120 may collect user information as context information. The processor 120 may compare the user information with question or answer information and may generate the compared result as additional information.

In operation 307, the processor 120 (e.g., an output module 125 of FIG. 2) may output at least one of a short answer or additional information. For example, the processor 120 may generate a voice signal corresponding to the short answer and may output the generated voice signal. The processor 120 may output a short answer, may convert additional information into a voice signal, and may output the voice signal corresponding to the additional information. According to various example embodiments, after outputting a short answer, if a specified condition is met, the processor 120 may output additional information. After outputting a short answer, if a user gesture for requesting to output additional information occurs, the processor 120 may output additional information.

If the analyzed result is not the specified short-answer question, in operation 309, the processor 120 (e.g., the question processing module 121) may determine whether the analyzed result is a specified descriptive question. For example, if a length of an answer corresponding to a question is greater than or equal to a specified length, if the answer is configured with a plurality of sentences, or if the answer includes a specified number or more of words, the processor 120 may determine the analyzed result as a descriptive question for a descriptive answer.

If the analyzed result is the specified descriptive question, in operation 311, the processor 120 (e.g., the output module 125) may obtain and output a descriptive answer using a database or a server. The processor 120 may convert the descriptive answer into a voice signal and may output the voice signal via an audio device 110 of FIG. 1. The processor 120 may search the at least one external electronic device 200 and may send a voice signal a device having voice signal output history or a device according to user selection among the at least one found external electronic device 200. According to various example embodiments, the processor 120 may generate additional information about a descriptive answer and may selectively output the generated additional information. When generating the additional information about the descriptive answer, the processor 120 may generate the additional information based on attributes information stored in the question database 131 or the answer database 133. The processor 120 may collect context information using a sensor 180 and the like of FIG. 1 and may generate additional information based on the collected context information and attribute information.

If the analyzed result is not the specified descriptive question, in operation 313, the processor 120 may collect an answer associated with the corresponding question in a specified manner and may output the answer to a specified device (e.g., the external electronic device 200). For example, if the answer includes an image, a formula, or the like, the processor 120 may configure a screen including the image or the formula. The processor 120 may output the screen on the display 160 or may send the screen to the at least one external electronic device 200 which may connect with the electronic device 100 via the communication interface 170. According to various example embodiments, if the answer includes a plurality of images or several formulas, the processor 120 may synchronize description information of describing the images or the formulas with the images or the formulas. While outputting a specific image or formula, the processor 120 may output a voice signal for the corresponding image and formula. If the output of the voice signal for the corresponding image or formula is ended, the processor 120 may output a next image or formula and may output a voice signal corresponding to the next image or formula.

FIG. 4 is a flowchart illustrating an example of a method for generating additional information according to an example embodiment.

Referring to FIG. 4, in the method for generating the additional information, in operation 401, a processor 120 (e.g., a question processing module 121) of FIG. 2 may collect at least one attributes information from a question or an answer. For example, the processor 120 may collect attributes information corresponding to a question or an answer using a question database 131 or an answer database 133 of FIG. 1. If attributes of the question are the same as attributes of the answer, the processor 120 may collect only one attributes information.

In operation 403, the processor 120 (e.g., an additional information generation module 123 of FIG. 2) may collect context information corresponding to the attributes information. For example, if attributes information is information indicating geography or a location, the processor 120 may collect information about a current location of a user of an electronic device 100 of FIG. 1 (e.g., a location of a home where he or she lives, a his or her location in the home, or the like). According to various embodiments, if the attributes information is information about a person, the processor 120 may operate a sensor 180 of FIG. 1 (e.g., a camera or an image sensor) to obtain face information of the user. If the attributes information is season or weather information, the processor 120 may operate the sensor 180 (e.g., a temperature sensor and a humidity sensor) to obtain information about temperature, humidity, illumination intensity, and the like.

In operation 405, the processor 120 may generate additional information based on the context information. If the context information is obtained, the processor 120 may generate additional information associated with an answer obtained based on the context information. For example, if the answer is information about a specified place name, the processor 120 may generate distance information from a current location of the user to a specified place as additional information. If the answer is information about a person, the processor 120 may compare a face of the person with a face of the user and may generate additional information (e.g., a description of a similar degree of a face) based on a matching degree. If the answer is weather information, the processor 120 may generate information about a current temperature and humidity as additional information.

In connection with generating the above-mentioned additional information, the electronic device 100 may include a database of defining attributes of the additional information, linked with attributes of a specific answer. The database of defining the attributes of the additional information may include a method of obtaining information corresponding to the attributes of the additional information. For example, the database of defining the attributes of the additional information may include a method designed to use a location sensor when additional information associated with a location is generated, a method designed to use a face recognition and comparison program when additional information associated with a person is generated, a method designed to use a temperature/humidity sensor when additional information associated with weather is generated, and the like. The database of defining the attributes of the additional information may be changed based on a user setting or may be updated by data provided from a specified server.

FIG. 5 is a flowchart illustrating another example of a method for generating additional information according to an example embodiment.

Referring to FIG. 5, in the method for generating the additional information, in operation 501, a processor 120 (e.g., a question processing module 121) of FIG. 2 may extract attributes information of at least one of an answer and a question. For example, if an answer is drawn based on an answer database 133 of FIG. 1, the processor 120 may extract attributes information corresponding to the drawn answer from the answer database 133.

In operation 503, the processor 120 (e.g., an additional information generation module 123 of FIG. 2) may select user information corresponding to the attributes information. In this regard, the electronic device 100 may store and manage a table in which attributes information stored in the answer database 133 is mapped to each of user information. According to an example embodiment, if the attributes of the answer are health, the processor 120 may obtain age, height, and weight information among user information. Also, if the attributes of the answer are sports, the processor 120 may obtain hobby information, special ability information, or the like among user information. If the attributes of the answer are economy, the processor 120 may obtain real estate information and the like based on home address information of a user of the electronic device 100.

In operation 505, the processor 120 may generate additional information based on the selected user and the answer based on a specified rule. For example, if a healthy weight for each age is an answer, the processor 120 may generate information about a heath state of the user as additional information with respect to his or her age, height, and weight. Also, if today's baseball situation is an answer, the processor 120 may generate information about actual results of other sports (e.g., football) teams selected by a hobby or preference of the user as additional information. Also, if a real estate price of a specific area is an answer, the processor 120 may generate real estate price information of an area the user lives currently as additional information.

FIG. 6 is a flowchart illustrating an example of a method for outputting a descriptive answer according to an example embodiment.

Referring to FIG. 6, in connection with the method for outputting the descriptive answer, in operation 601, a processor 120 (e.g., a question processing module 121) of FIG. 2 may collect a descriptive answer. For example, the processor 120 may collect a descriptive answer mapped to a corresponding question based on a question database 131 and an answer database 133 of FIG. 1 corresponding to an analysis of a collected voice signal and the analyzed result. If there is no data associated with a question or an answer in the question database 131 or the answer database 133, the processor 120 may send a user voice signal (or a result of analyzing the voice signal) to a server via a communication interface 170 of FIG. 1 and may collect an answer corresponding to the user voice signal.

In operation 603, the processor 120 (e.g., the question processing module 121) may determine whether the collected descriptive answer is a time series answer. For example, the processor 120 may determine whether specified words (e.g., a stage, an operation, a process, and the like) indicating the time series answer are included in the descriptive answer. Alternatively, the processor 120 may determine whether specified numbers, for example, “1.1”, “1-1”, “a) and b)”, “A) and B)”, or the like, indicating the time series answer are included in the descriptive answer. The processor 120 may determine whether a plurality of conjunctions associated with the time series answer are included in the answer.

If the collected descriptive answer is the time series answer, in operation 605, the processor 120 (e.g., an output module of FIG. 2) may output a first-stage answer in a multistage descriptive answer. For example, the processor 120 may determine a range from a start portion of an answer to a period, a range before a specified conjunction, or a range before a specified number as a first stage. The processor 120 may convert text corresponding to the determined first stage into a voice signal and may output the converted voice signal. According to various example embodiments, if the first-stage answer is configured with a voice signal, the processor 120 may output the voice signal corresponding to the answer to a specified device (e.g., at least one external electronic device 200). According to various example embodiments, if an image, a formula, or the like is included in the answer, the processor 120 may provide a screen corresponding to the corresponding image or formula to the specified external electronic device 200 or may send address information (or link information) corresponding to the corresponding image or formula to the specified external electronic device 200.

After outputting the first-stage answer, in operation 607, the processor 120 (e.g., the output module 125) may determine whether a specified condition is met. The specified condition may include, for example, a condition of determining whether specified user gesture information is collected. In this regard, the processor 120 may operate a sensor 180 (e.g., a camera or an image sensor) to collect an image for a face, hand, body, or the like of a user of an electronic device 100 of FIG. 1 and may determine whether the user performs a specific gesture based on analyzing the corresponding image. According to various example embodiments, the specified condition may include a condition of collecting a specified voice signal. In this regard, after the outputting the first-stage answer, the processor 120 may activate an audio device 110 of FIG. 1 to collect a user voice signal and may determine whether a voice signal corresponding to the specified condition is included in the collected voice signals.

According to various example embodiments, the processor 120 may determine whether a user gesture corresponding to a word included in the first-stage answer (e.g., a word associated with an operation). If the user gesture corresponding to the word included in the corresponding stage is collected, the processor 120 may determine whether the specified condition is met. In this regard, the processor 120 may operate an image sensor included the electronic device 100 or may receive sensor information (e.g., acceleration sensor information, geomagnetic sensor information, heartbeat information, or the like) from an electronic device held by the user.

If the specified condition is met, in operation 609, the processor 120 may determine whether a next-stage answer is a final-stage answer. If the next-stage answer is the final-stage answer of the descriptive answer, in operation 611, the processor 120 may output the final-stage answer. For example, the processor 120 may output a voice signal corresponding to the corresponding answer (e.g., convert text into a voice signal and output the converted voice signal). If the next-stage answer is not the final-stage answer, in operation 613, the processor 120 may output the next-stage answer and may branch to operation 607 to perform the operation from operation 607.

If the specified condition is not met in operation 607, in operation 615, the processor 120 may determine whether an event associated with an end occurs. If the event associated with the end does not occur, the processor 120 may branch to operation 607 to perform the operation from operation 607. For example, the processor 120 may determine whether the specified condition is met, in real time or at a period.

If the descriptive answer is not the time series answer in operation 603, in operation 617, the processor 120 (e.g., an addition information generation module 123 of FIG. 2) may generate additional information based on attributes of a question and attributes of a descriptive answer. For example, if a descriptive answer associated with a specific trail is received in response to a question associated with the corresponding trail, the processor 120 may generate a recommended trail as additional information based on an amount of usual exercise of the user. The amount of usual exercise of the user may be obtained from information stored by a healthcare program. In operation 619, the processor 120 may output at least one of the descriptive answer or the additional information.

According to various example embodiments, the time series answer may include a recipe for pasta. In this example, the processor 120 may monitor camera information and sensor information while inputting and outputting information about materials for preparing a recipe and an order of making pasta in a queue (not shown) of the electronic device 100 and may determine a cooking progress situation. The processor 120 may output an answer based on story telling for each cooling stage. In this operation, the processor 120 may compare answered contents with a degree of current progress and may store next-stage story telling (e.g., next story text) in a queue (or buffer) if current-stage cooking is not ended.

According to an example embodiment, in case of a descriptive answer (e.g., recipe information and the like), the processor 120 may wait without completing an answer in the middle. In this example, if a user voice signal for another question is collected, the processor 120 may search for an answer in response to the user voice signal and may output the found answer. In this regard, the processor 120 may actively change a queue order of a descriptive answer and an additional answer. For example, in a situation where the processor 120 waits for an answer No. 3 after an answer No. 2 is completed while cooking having a plurality of stages progresses, if receiving a middle question, the processor 120 may obtain and output an answer to the middle question and may wait for the answer No. 3 again. For example, if receiving a weather question during a cooking stage, the processor 120 may delay a queue of the answer No. 3 and may output a current temperature and weather information. If an answer to the middle question is completed, the processor 120 may restore the queue of the answer No. 3 to an original location. After completing the answer No. 2, the processor 120 may resume monitoring a progress state (e.g., collect and analyze user related context information).

FIG. 7 is a flowchart illustrating another example of a method for outputting a descriptive answer according to an example embodiment.

Referring to FIG. 7, in connection with the method for outputting the descriptive answer, in operation 701, a processor 120 (e.g., a question processing module 121) of FIG. 2 may collect a descriptive answer. For example, the processor 120 may collect a descriptive answer corresponding to a collected voice signal based on a question database 131 and an answer database 133 of FIG. 1.

In operation 703, the processor 120 (e.g., an output module 125 of FIG. 2) may search a peripheral external electronic device. The processor 120 may search at least one external electronic device located within a distance using a short-distance communication module included in a communication interface 170 of FIG. 1.

In operation 705, the processor 120 may select the external electronic device. For example, the processor 120 may select the number of peripheral external electronic devices or a type of an external electronic device in a different way based on attributes of the collected descriptive answer. For example, the processor 120 may select the number of external electronic devices or a type of an external electronic device based on the entire length of the descriptive answer. According to an example embodiment, if the entire length of the descriptive answer is greater than or equal to a specified length, the processor 120 may select a relatively greater number of external electronic devices. If the entire length of the descriptive answer is less than the specified length, the processor 120 may select a relatively fewer number of external electronic devices. Also, if the descriptive answer is an answer with a cadence (e.g., a sijo, a song, and the like), the processor 120 may select an external electronic device with external excellent speaker quality.

In operation 707, the processor 120 may send the descriptive answer to the external electronic device 200. In this regard, the processor 120 may establish a communication channel with the external electronic device 200 using a short-distance communication module (or a communication module supporting an Internet network and the like) and may send the descriptive answer to the external electronic device 200 based on the communication channel. According to various example embodiments, a QA processing system may further include an Internet of things (IoT) hub (or at least one processor). The electronic device 100 and the at least one external electronic device 200 may establish a communication channel with the IoT hub. In such environment, the electronic device 100 may send the descriptive answer to the IoT hub. The IoT hub may send the descriptive answer to the at least one specified external device 200. According to an example embodiment, the IoT hub may determine attributes of the descriptive answer provided from the electronic device 100 and may send the descriptive answer to the at least one specified external electronic device 200 based on the determined attributes. In this regard, the IoT may store information about attributes of descriptive answers and mapping information associated with external electronic device selected by the corresponding attributes in its database. According to various example embodiments, the IoT hub may send the received descriptive answer to the external electronic device 200 selected by the electronic device 100 based on a descriptive answer provided from the electronic device 100 and a list of the at least one external electronic device 200. The electronic device 100 and the at least one external electronic device 200 may connect with the IoT hub wiredly or wirelessly.

FIG. 8 is a flowchart illustrating another example of a method for outputting a descriptive answer according to an example embodiment.

Referring to FIG. 8, in connection with the method for outputting the descriptive answer in case of no short answer or descriptive answer, in operation 801, a processor 120 (e.g., a question processing module 121) of FIG. 2 may collect answer address information. According to an example embodiment, if at least part of an answer to a question includes an image, a formula, or the like, the processor 120 may obtain address information of a location (e.g., uniform resource locator (URL) information, sound quick response (QR) information, or the like) which stores the answer. The address information may include address information of an answer database 133 of an electronic device 100 of FIG. 1, which may store the answer, address information of an external electronic device 200 of FIG. 1, address information of a specified server, or the like.

In operation 803, the processor 120 may output the address information. For example, the processor 120 may output the address information to a specified device (e.g., the external electronic device 200 or the like). In the output process, the processor 120 may output the address information as link information. According to an embodiment, the processor 120 may display linked information corresponding to the address information. When the address information is selected, the processor 120 may display screen related to the linked information.

In operation 805, the processor 120 may obtain information of whether an input signal associated with selecting the address information is generated. If the input signal associated with selecting the address information is generated, in operation 807, the processor 120 may control an output of information corresponding to the address information. According to various example embodiments, the processor 120 may output the address information on the display 160. If a touch input for selecting the corresponding address information occurs on the display 160, the processor 120 may output answer information corresponding to the address information on the display 160. According to various example embodiments, the processor 120 may send the address information to the specified external device 200. The external electronic device 200 may output the received address information on its display and may collect and output answer information corresponding to the address information based on a user input. In this regard, the external electronic device 200 may establish a communication channel with the electronic device 100, another external electronic device, a server, or the like based on the address information and may receive answer information from the corresponding device. According to various example embodiments, the processor 120 may receive a user input signal from an external electronic device which outputs address information and may send answer information to the external electronic device in response to the user input signal.

If the address information is not selected, the processor 120 may omit operation 807. The processor 120 may maintain the output of the address information during a specified time. If the specified time elapses, the processor 120 may stop outputting the address information. According to various example embodiments, the processor 120 may store and manage the address information which is not selected. The processor 120 may output a list of address information on the display 160 based on a user input. If the user input (e.g., an input associated with selecting address information) occurs, the processor 120 may perform operation 807 above.

FIG. 9 is a flowchart illustrating an example of an information output method according to an example embodiment.

Referring to FIG. 9, in the information output method, in operation 901, a processor 120 (e.g., an output module 125) of FIG. 2 may extract information in which it is impossible to perform text to speech (TTS) conversion. For example, if obtaining an answer to a question based on an answer database 133, the processor 120 may analyze the obtained answer and may determine whether specified information (e.g., an image, a formula, a special letter, and the like) in which it is impossible to perform TTS conversion is included in the answer. If the specified information is included in the answer, the processor 120 may extract the corresponding information from the answer. Also, the processor 120 may collect a location in content of the specified information. The processor 120 may collect text located in a front end of the specified information, text located in a rear end of the specified information, and the like.

In operation 903, the processor 120 may synchronize the extracted information with TTS conversion information. For example, the processor 120 may convert information in which it is possible to perform TTS conversion, except for the specified information, into a voice signal. Also, the processor 120 may perform a synchronization process of adjusting a time when the converted voice signal is input based on location information of the specified information.

In operation 905, the processor 120 may output the extracted information to a specified device while outputting the TTS conversion information. For example, the processor 120 may output specified information associated with the voice signal on a screen of the specified device while outputting part of the converted voice signal. If the output of the voice signal associated with the specified information is completed, the processor 120 the processor 120 may output a voice signal associated with subsequent specified information while outputting the subsequent specified information.

According to various example embodiments, if an external electronic device which outputs an answer in which it is difficult to perform TTS conversion is not found, the processor 120 may send the corresponding answer using an electronic mail (email) of a specified account. As described above, the electronic device 100 according to various example embodiments may represent a formula, a mathematical proof, a descriptive answer, or the like in which it is difficult to be represented by conversation, using a push service such as a URL or a sound QR via a device, such as a mobile phone and a tablet personal computer (PC), in which it is easy to be represented by conversion. The electronic device 100 may provide information in which it is difficult to be represented by TTS in the form of a URL or in the form of being able to be output. Also, the electronic device 100 may provide the information, in which it is difficult to be represented by the TTS, as a file (e.g., a DOC file, a JPG file, a PDF file, or the like) of a form which may be output to support to verify and output an answer in an offline environment where the Internet does not connect with the electronic device 100.

FIG. 10A is a flowchart illustrating another example of a QA processing method according to an example embodiment.

Referring to FIG. 10A, in the QA processing method, in operation 1001, a processor 120 (e.g., a question processing module 121) of FIG. 2 may determine whether a voice is collected. If the voice is not collected, the processor 120 may maintain a previous operation. While maintaining a sleep state, the processor 120 may maintain only an audio device 110 of FIG. 2 in an idle state.

If the voice is collected, in operation 1003, the processor 120 may collect context information. If a user voice signal is received, the processor 120 may obtain a user related image or may collect user related information, using a sensor 180 of FIG. 1 (e.g., an image sensor, a location information sensor, or the like).

In operation 1005, the processor 120 may analyze voice information based on context information. In this regard, the processor 120 may convert the received user voice signal into text. The processor 120 may configure a question based on the converted text.

In operation 1007, the processor 120 may select one of a short answer or a descriptive answer based on the result of analyzing the information. For example, the processor 120 may search a question database 131 and an answer database 133 of FIG. 1 or a server for an answer to a question and may select at least one of a short answer or a descriptive answer in response to the context information. For example, if a question on a location of a bus of a specific number is collected and if a user of an electronic device 100 of FIG. 1 is located in his or her living room, the processor 120 may communicate with a bus management server to obtain a short answer to a time when the bus of the corresponding number arrives at a bus stop. If the user is currently located in his or her dressing room, the processor 120 may communicate with the bus management server to obtain a plurality of answers to times when buses of the corresponding number will arrive at a specified bus stop. Also, the processor 120 may obtain an answer to a state where seats of each bus are occupied. In operation 1009, the processor 120 may output a corresponding answer in a specified manner based on a type of a selected answer.

FIG. 10B is a flowchart illustrating another example of a QA processing method according to an example embodiment.

Referring to FIG. 10B, in operation 1051, a processor 120 (e.g., a question processing module 121) of FIG. 2 may obtain a voice signal corresponding to a user of an electronic device 100 of FIG. 1. For example, the processor 120 may collect a voice signal (or a user command) of the user using a microphone of the electronic device 100 or may receive a voice signal or text via a communication interface 170 of the electronic device 100 from an external device (e.g., the external electronic device 200).

In operation 1053, the processor 120 (e.g., the question processing module 121) may obtain context information associated with the user, in connection with obtaining the voice signal. For example, the processor 120 may analyze the obtained user voice signal or text and may extract a question from the voice signal. The processor 120 may analyze attributes information of a question and may obtain user information associated with the attributes information from the memory 130. The processor 120 may obtain context information (e.g., image information) associated with the attributes information of the question.

In operation 1055, the processor 120 (e.g., the question processing module 121) may determine whether the context information meets a first specified condition or a second specified condition. For example, the first specified condition may include a condition in which a response length of a question is within a length. The first specified condition may include a condition in which a user who asks is a first specified user. The first specified condition may include a condition in which an asked location is a first specified location. The first specified condition may include a first condition in which a special letter or an image is not included in a question or an answer to the question. The first specified condition may include a condition in which the user who asks takes a gesture or pose of the first specified condition. The second specified condition may include a condition in which a response length of a question is greater than or equal to a length. The second specified condition in which the user who asks is a second specified condition. The second specified condition may include a condition in which the asked location is a second specified location. The second specified condition may include a second condition in which a special letter or an image is included in a question or an answer to the question. The second specified condition may include a condition in which the user who asks takes a gesture or pose of the second specified condition.

If the context information meets the first specified condition, in operation 1057, the processor 120 (e.g., an output module 125 of FIG. 1) may output at least part of information corresponding to the command signal. According to various embodiments, the processor 120 (e.g., an additional information generation module 123) of FIG. 2 may obtain an answer based on the first specified condition and may generate additional information based on the first condition, associated with a question or an answer associated with the first specified condition. The processor 120 may output at least part of an answer to a question or the additional information according to the first condition.

If the context information meets the second specified condition, in operation 1059, the processor 120 (e.g., the output module 125) may output at least part of second answer information corresponding to the voice signal. According to various embodiments, the processor 120 (e.g., the additional information generation module 123) may obtain an answer based on the second specified condition and may generate additional information according to the second condition, associated with a question or answer associated with the second specified condition. The processor 120 may output at least part of an answer to a question or the additional information according to the second condition. The processor 120 (e.g., the output module 125) may output at least one of types of external electronic devices or the number of the external electronic devices, output based on the first specified condition and the second specified condition, in a different way.

Operations (e.g., operations 301 to 313, operations 401 to 405, operations 501 to 505, operations 601 to 619, operations 701 to 707, operations 801 to 807, operations 901 to 905, or operations 1001 to 1009) described in processes or methods shown in FIGS. 3 to 10B may be executed by a successive method, a parallel method, a repeated method, or a heuristic method. For example, the operations may be executed in a different order, some operations may be omitted from the operations, or other operations may be added to the operations.

According to various example embodiments, a QA processing method may include: obtaining a voice signal corresponding to a user, obtaining context information associated with the user in connection with obtaining the voice signal, determining whether the context information meets a first specified condition or a second specified condition, and outputting at least part of first answer information corresponding to the voice signal if the context information meets the first specified condition and outputting at least part of second response information corresponding to the voice signal if the context information meets the second specified condition.

According to various example embodiments, the obtaining of the voice signal may include receiving the voice signal from the user using a microphone of the electronic device.

According to various example embodiments, the attributes information may include a text length of the answer information, information indicating whether a special letter is included, a category, or combinations thereof. The QA processing method may further include generating information corresponding to the specified condition based on at least part of the attributes information.

According to various example embodiments, the outputting may include outputting information which is not converted into a voice signal among additional information on a screen of a specified device or outputting address information corresponding to a storage location in which the additional information is stored on the screen of the specified device.

According to various example embodiments, the above-mentioned QA processing method may include sharing a database with a memory (or a storage device) of a peripheral electronic device in connection with generating additional information and generating additional information based on the shared database, identifying a speaker through voice and face recognition of a user who asks and discriminately providing an answer for each identified speaker, and storing and managing answer history and generating additional information based on the stored and managed answer history.

According to various example embodiments, the above-mentioned QA processing method may be configured to generate additional information in connection with an answer output for each stage in connection with generating the additional information and to generate the additional information to change a form of provided additional information, based on user information of a monitored user (e.g., a body condition, an age, a location in family members, a hobby, a preference, and the like). For example, the QA processing method may include changing a detail drawing of a description for each stage based on user information if additional information associated with a song lecture, block assembly, or the like is generated. The QA processing method may include applying a setting condition of entering a subsequent stage in a time series answer of entering the subsequent stage after specified context information should be obtained to user information in a different way (e.g., providing an easier setting condition to a relatively younger or more unskilled user and providing a more difficult setting condition to a relatively older or more skilled user).
